Replying to [henryhe]:Firstly, Which market are you target on? North America, Western Europe, Australia, Asia Japan, Middle Asia or Southern Asia, Africa, India??? (Just think about it)
1) North America, Western Europe, Australia or Asia Japan Market -
you may try to register a patent for your products, which aimed to prevent the buyers buying non-license products. Which may help a little bit to your business.
2) For markets in Middle & Southern Asia, India, Africa - please forget the patent, it is useless, the only way is to try your best cover most of the market share by providing your lowest price, best quality, newest products range instead of wanna to stop copying. The fact is who care who designs the products in those regions...
Finally, you don't want somebody copy your idea, try to make your product in secrets, only serve existing customers for your new idea, remember to remind your clients not to disclose your idea to anyone else.
that is...try your best...
